FAQs

  • Whether you're customizing an existing piece from our engagement collection or designing a completely new ring from scratch, our team will guide you through every step of the process. We start with a consultation to discuss your vision—don’t worry if it’s not yet fully defined. We'll cover your vision, timeline, budget, and answer any questions you have about the custom design and production process. Afterward, we’ll draft designs and/or source stones for your review before beginning production with our team of master jewelers.

  • The custom design and stone selection process typically takes a few weeks, depending on your unique piece and its specifications. Once production begins, the standard lead time for a Steph Mazuera Custom Engagement Ring is 4-8 weeks, though this may vary based on the design specifications. Please feel free to reach out and let us know if you have a specific timeline or goal in mind.

  • We most typically work with lab diamonds, but can source mined diamonds or antique diamonds upon request.

    We also love to work with clients who bring their own heirloom stones to be repurposed into new pieces. 

  • The only difference between lab diamonds and mined diamonds are their origins - both lab diamonds and mined diamonds contain the same physical and chemical properties.  There are no optical differences between mined diamonds and lab diamonds when grown correctly. 

    There is more to buying a diamond than just the 4cs and not every Lab Diamond is produced to the same standards. Lab diamond quality can vary significantly by source and level of care taken during the growth process - every stone sourced by Steph Mazuera is closely examined to ensure it meets our strict quality standards. 

  • Not always. Each ring we produce, custom or not, is made to the exact specifications of the diamond it holds - if you’d like to make changes like swapping a diamond cut or adding an engraving we can certainly arrange that. 

  • With our bespoke services, we can customize every part of your engagement ring to your liking. Some of our favorite personal touches include interior engraving and hidden birthstones. If you’d like to add a personalized touch to one of our existing collection rings please contact us.
